Abstract:

A size-reduced ultra-wideband three-element antenna is described. Each resonator element is a half-wave dipole, tuned to long, medium and short wave points in the frequency band, respectively. Size reduction of the dipoles is effected by employing a slow-wave helical structure wound coaxially on an insulated tube. The helices are short-circuited at their outer ends to achieve broadbanding. The reported match of this antenna over 4-5 octaves is 1.5 VSWR. Author
